[Asterisk-Users] Scaleable Solution for small office

Tim,

For my home office it would cost a lot more to go that route. I'm
thinking of a 4 port FXO adapter instead of the 3 or 4 X100's. I see
such gateway devices for $600-800. I suspect the channel bank and T1
card would be overkill for such a small situation.

It might end up costing a little more, but I would strongly suggest
looking into the T100P/Channelbank combination instead of the X100P
cards&especially for business class service.  

   

   

I too had the same issues w/ the X100P, although I have not experienced
problems w/ the latest CVS.  I still will install/sell only T100P cards
and channelbanks to businesses, especially if they will use VOIP at
their location.  

   

I believe the extra dollars you spend on the equipment will more than
make up for the time you will spend on troubleshooting problems related
to echos.

Hi,  

   

Have posted to this list a couple of times and have always received
great responses and help.  I have a basic * system setup  

Using 3 X100P cards with 6 Snom200 IP phones.  It was a bit of a
struggle getting everything up and running but have been pretty happy
with 

the flexibility and ease of *.  My major problem is one that has been
discussed on this list many times before.  The echo from the X100P
cards is 

completely irritating to my users.  I have tweaked the system as much
as I can, IE: switching tip and ring, using aggressive suppressor,
tweaking the TX/RX 

settings.  There is still echo in the first 0-8 seconds of the call
while the echo cancellation is catching up.  I understand the problem
is that you do not hear this 

echo in analog systems even though it is present and it is only heard
in the digital system because it is not as fast as analog.  

   

So here is my problem.  Our CEO wants me to get rid of the system
unless I can provide a solution that will expand and work just as good
as an analog replacement  

PBX.  He came to me with this decision after trying to use the Snom200
speaker phone for a conference call, not a good idea as we all know the
speaker on this phone     

is not a conference phone replacement.  He also was frustrated when he
tried to patch a call that came to another extension, which transferred
fine, but was disconnected when the receiving party made a switch on
their PBX to another extension and it was dropped.  

   

Currently we have 4 POTS lines and I have 1 setup for DSL and the other
3 hooked into the X100P cards, 2 outgoing and 2 incoming, using the DSL
as incoming rollover.  

We are planning on expanding our business pretty rapidly and he wants a
system that will be easy to setup and scale.  I know asterisk and VOIP
phones are great for this  

but the little glitches in the phones, hardware wise, are not
supporting my Asterisk decision.  I would like to upgrade to a channel
bank, and was wondering if anyone has had any echo issues with other
digium hardware.  I know that the X100P issue comes from not having
ECAN DSP in the card.  I was also wondering if anyone had any luck
adding a conference phone such as the Polycom Soundstation Conference
Phone.  Any suggestions would be appreciated
